 There are two types of cache in your computer: level 1 and level 2. The level 1 cache (also known as L1 cache) is inside the CPU itself, and you really ddrramreview have no control over quantity and speed. The level 2 cache (also known as L2 cache) are all external to the chip. The L2 cache on the nside the CPU package (though still external to the CPU chip itself). Those systems run on motherboards with a variety of core logic chipsets. However, some of them are designed so that the L2 cache only works with the first 64MB of RAM in your system. The two main culprits are the chipsets—two of the ddrramreview most common chipsets available. Now, 64MB is a lot of RAM, so it''s not like your system is somehow crippled (at least, not for gaming). But you should be aware that in the case of boards using these chipsets, more is not necessarily better. motherboards with the chipset probably can cache up to 512KB of RAM, but a few motherboard makers cheaped out and left out a critical TAG RAM chip and—you guessed it—those boards can only cache the first 64MB or RAM. To my knowledge, boards that use the can cache more than 64MB, but be wary. What is SDRAM? SDRAM is an acronym for Synchronous Dynamic Random Access Memory. The term "Synchronous" means that the clock cycle of the memory is exactly synchronized with the clock ddrramreview and ddrramreview cycle of the bus. Every calculation and operation a PC performs is timed according to a clock ticking millions of times each second, its clock cycle or megahertz rating. If the memory clock cycle is not in sync with the bus clock cycle, system problems will occur. What is Cache Memory? Cache, pronounced "cash", is a high-speed memory designed to supply the processor with the most frequently ddrramreview requested data and instructions. The information located in the cache memory can be accessed many times faster than information in the system''s main memory. The more information your system can retrieve from the cache memory, the more efficient the system will run. Level 1 (L1) cache, also referred to as Primary Cache, is normally located inside the CPU chip. Level 2 (L2) cache, also referred to as Secondary Cache, was normally located on the system board near the CPU in the past. In today''s systems, both are physically located within the CPU and as a result are not upgradable. Professional / Feel the need for Speed! If you are running multiple business applications, want to play the newer video games and/or work with graphics, you can get by with 256MB, but your computer speed would benefit greatly by having 512MB. Advanced Professional If you work with high-end graphics, software, digital images, or video, you can get by with 256MB, but would benefit greatly by installing 512MB of memory or more. Right now our 512MB memory modules are available at incredibly low prices. Graphics Design Professional If you are, or plan to be, a professional graphics designer, use CAD or modeling software, digital images or video, you can get by with 512MB, but would benefit from going to 1GB of memory or more. Will adding more RAM make my Internet surfing faster? The short answer is maybe. Internet browsing speed depends on a huge number of factors, including your connection speed, traffic on the site you''re visiting, and the other components in your system. You will probably notice the biggest improvement from additional RAM if are viewing or working with large files (such as photos and digital audio and video) or if you switch between your browser and other applications often, like to play games, or want to use your computer for viewing photos. Would you like to find ddr, simm or dimm memory but aren't sure where to look? Search no further. We have any type of memory for any computer you have.
